No even @calle agrees that the biggest risk with ecash is being debased (not on the sats end, but by the mint printing extra tokens to give to themselves).

Lets talk in specifics: What exactly is a "eCash Mint"?

It is a python script that accepts LN and issues signatures....thats it. There is nothing stopping the python script from issuing 1.05x signatures for every sat that is received. That 5% extra issuance would be impossible for any users to detect.
