Thanks for the explanation @levi @infinite
I’m mentioning below comment which summarizes my worries - for example I can image FE (DEX, Wallet,…) which doesn’t get the parameters dynamically, has separated variables (or hardcoded value) for icrc1_decimals per operation, updates it for reads/displaying and leaves old values for writes/sending - causing discrepancy in SNS1 token-quantums which would be processed.
I mean I’m supportive for any solution which will be chosen, just would like to express need for throughout (ecosystem-wide) testing in case of change to current SNS1 parameters/tokenomics
