I've created PR here DefinitelyTyped/DefinitelyTyped#41418, which fails CI build check as the package version is prelease one (previously it was tagged as alpha, now as rc): 1.0.0-rc.2.
The check fails because of strict version check, which does not coerce prelease versions as in https://github.com/npm/node-semver/blob/70d9fb3f1c128227a3cd911867edb07a54260cad/classes/semver.js

Is that version check outcome expected (I'd close the issue) or should it be somehow addressed?
Thanks!

Somehow similar, already tracked issue:
