for those developing SuiteApps or large SuiteScript solutions, have most of you made the conversion to fully adopt SuiteScript

2.1

? I have not revisited since a Release or so ago, seemed to be some bugs/errors that occurred at the time when attempting to convert, maybe these have all been addressed by now? just looking to see if there is a consensus reached out there and 2.1 is good to go :) Thanks

I'm using 2.1 by default for some time now.

For the past year and a half we have been using 2.1 exclusively (except for Client scripts and GL plug-ins) and have not had any issues since then.

even client scripts support 2.1 as of 2021.1

Yep. Same here as @stalbert. In fact, since we're a TypeScript shop, I made some simple changes to our

tsconfig.json

file, and we instantly were producing 2.1 compliant code. Zero effort, with all the benefits.
