I don't know if we need to have some sort of triage conversation in the team here, we don't typically add this type of feature on a very ad-hoc basis but this does make sense to me to add in general

[FGasper]

@addaleax Triage: by all means. I just wanted to PoC the idea to get the ball rolling.

[addaleax]

We can't really do a semver comparison here, right? Otherwise I think that would be highly preferable.

If we leave this as-is, I'd leave a comment in

mongosh/packages/build/src/download-center/config.ts

Line 205 in e9dfc41

currentVersions.sort((a, b) => semver.rcompare(a.version, b.version));

about this script depending on that specific ordering

(@addaleax added the comment since jQ is a funky—if poetic, heh—place to do things like semver sorting.)

[gagik]

would it make sense to have this run every day etc. as a health check?

@gagik Sure: 2a71d49

This should be pretty useful!
