For Android. My rationale is available at QuickLyric/QuickLyric#271 (comment).

I don't know about the possibilities, but if not too much of a burden I (and probably others too) would prefer to keep the original Material design.

Material design 3 does not only introduce customizable colors, but also many other changes that are not customizable however quite ugly: these include unnecessary larger whitespaces, and largely rounded corners.

Contrary to the above rationale, from my side at least sticking with Material (1) does not mean that the software is unmaintained, and I don't think many are thinking that way. In my opinion, the appearance of the software is consistent with the latest tasteful version of the Material Design Guidelines.
The app's current version may not be fashionable, but usability is unaffected.

@mpeter50, I'd say that it's more https://m2.material.io/design/introduction#baseline-grid than https://m1.material.io/material-design/introduction.html.
