What would be a drawback if sum instead of SHA-256 of amounts was used the TapRoot signature message?

Would there be any drawback of using sum of amounts instead of SHA-256 of amounts in the TapRoot signature message? There is the sha_amounts (32): the SHA256 of the serialization of all input amounts. specified in the BIP-341: https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki#common-signature-message. SHA-256 seems more expensive than e.g. sum_amount (8): sum of all input amounts.

Bitcoin Mining May Support The Ruble Responding to a question at a press conference, Nabiullina said it is “probably difficult to quantify” mining’s influence “because a significant part of mining is still in a gray area.” Still, she added that mining is “indeed one of the additional factors contributing to the strong ruble exchange rate.” As Russian business news portal for RBC reported , her remarks come as Russian officials increasingly frame mining and crypto flows as macro-relevant, not just a niche tech or energy story. Earlier, Maxim Oreshkin, deputy head of the presidential administration, said ruble forecasts have been thrown off by the underestimation of financial flows tied to mining and cryptocurrency. In his view, the s...
