Did the P2SH BIP-0016 make some Bitcoin unspendable?

The P2SH feature currently in use was introduced to Bitcoin in 2012 with BIP-0016. It was successfully activated on 2012-04-01 with block 173805.

The BIP turned a particular "hashlock" locking script pattern (OP_HASH160 OP_DATA_20 20-byte-value OP_EQUAL) into a "magical" bytecode pattern which, after authenticating an input's top stack element against the hash then also executes it using Script VM.

The BIP references 1 historical transaction that spent from an output that matched the pattern:

These new rules should only be applied when validating transactions in blocks with timestamps >= 1333238400 (Apr 1 2012) [1]. There are transactions earlier than 1333238400 in the block chain that fail these new validation rules. [2]. Older transactions must be validated under the old rules. (see the Backwards Compatibility section for details).

which made me wonder - are there other, unspent, historical hashlock outputs which may have been made unspendable (if they weren't already) by introduction of the P2SH feature?

Do Kwon’s Detention Prolonged Until 2024 As Montenegro Responds To Extradition Requests

According to an International Business Times report , Montenegro’s Supreme Court decided to extend the detention of TerraForm Labs founder and CEO Do Kwon until February 2024, following extradition requests from the United States and South Korea. Closed-Door Discussions Reveal Montenegro’s Plan For Do Kwon Initially set to be extradited to the US on December 15, Do Kwon’s fate turned when the Montenegrin High Court ruled to prolong his stay until February 15, 2024. The decision stems from charges related to the collapse of the TerraUSD stablecoin, which led to significant financial losses. The High Court had previously ordered Kwon’s extradition by Friday, but his defense team appealed the decision in the appellate court in Podgorica, the capital of Montenegro. The Montenegrin Court of Appeal confirmed that Kwon contested the High Court’s ruling, vehemently stating, “I do not submit to the court’s decision.” Recent reports indicate that Montenegro’s Justice Minister, Andrej Mil

Sam Bankman-Fried Trial Begins Tomorrow: 3 Reasons Ex-SEC Official Foresees Conviction

Image
The trial of Sam Bankman-Fried, the founder of cryptocurrency exchange FTX and hedge fund Alameda Research, is set to commence in New York on Tuesday, October 3.  This comes almost a year after the collapse of both FTX and Alameda Research. The events leading up to the trial paint a picture of alleged fraudulent activities and money laundering that caused significant damage to the businesses involved. Ex-SEC Official’s Bleak Prediction As Sam Bankman-Fried Trial Commences In a nutshell, Alameda Research purportedly took customer deposits from FTX and invested them in fictitious crypto tokens, which derived their value from the confidence in FTX’s operations.  When this confidence waned, FTX and Alameda Research suffered substantial losses, which many argue contributed to a broader disillusionment in the cryptocurrency industry.  Following an investigation, federal authorities uncovered numerous alleged crimes, leading to seven federal fraud and money-laundering charges against B
