This is the kind of stuff I would add in the commit message (and PR description): "I ended up choosing solution A because B, I also tried C and D, but that didn't work so well because E".

Everything you say that's not written down will be lost in the aether within weeks, months at best. I'm a huge fan of async communication because everything will be written down.

If there's a discussion "why did you go with A and not B", in an (async) code review then anyone can come back to it a year later and read up on why it was done in this particular way. I've found this useful on a number of occasions.

It certainly beats "Alice, you changed this last year, but why is it done like that? Wouldn't X be much more convenient because Y? It's hard to add Z now.", "ehm, I discussed it with Bob, but he since left the company. I don't quite remember, I think it was A? Or maybe B? Or was it C?"
