Without being simplistic - isn't this a case of "right tool for right job"?

You can pay me to build you SAP in Excel, but you really shouldn't!

If you have a 100mb password database, should you be moving to a more scalable solution?

I think a relational DB is the best tool for the job!

I argue more for the use case of "secrets manager" than solely password manager. People store TOTP seeds and Passkeys and a myriad attachments. A SQLite store would better facilitate this, as not everything has to be in memory all the time. This is only with regard to the size constraint, there are so many other benefits to be had from a formal specification of the schema to truly future-proof the standard.
