It's interesting if you got a lot of wheels to build locally, but this is very specific: most wheels are pre-built for you, that kinda the point.

It still happens from time to time, but if somebody else read this comment, you want to check how many wheels you build before doing so.

Also, you may want to cache those build once and for all.

Depends on your platform. If you're using ARM (like AWS Graviton, and possibly Apple M1) you might find that many wheels are not available. That might be different now, my information is 2 years old, but I remember 'pip install numpy' taking ages. Every time someone pushed a change we'd have a 15 minute job clogging the pipes. Luckily I had already created an artifact repo (AWS CodeArtifact) for our own internalpackages, so I added a step to our build process to push locally built wheels, so a painfully slow build would only happen once.
