[core-workflow] How long to wait for any reaction to a (new) PR?

a) Hope this is the right place! b) I assume everyone is very busy so I would never assume a reaction with one to two weeks, but - how long is "normal" before asking for a TTT, or something. As an aside - I see that when it takes too long (call it unlucky) something that worked is suddenly "in conflict". More specific, was submitted against 'master' before the 3.7 tag was introduced - and now the master has moved far enough that CI says it cannot merge aka merge conflicts. Again, I understand this is life, but I do not want to make unnecessary noise. If you say, it comes when it comes then I'll just have to wait. Til tomorrow! Michael
