I agree that training, in general, is not really effective. You have to actually use the things you've been training for immediately afterwards to gain any benefit. If 2 - 3 weeks go by, you've already forgotten a lot of the training.

How my company is trying to deal with that is by creating a library of self-paced training modules maintained by software engineers, and facilities to help anyone do that. I'm not sure it's going to achieve exactly what the OP is asking about, but I think it's better than alternatives.

We also have a private Stack Exchange server, frequent tech meetups, internal support slack channels and a bunch of other ways to interact with internal platform teams that help quite a bit.

Still, you have to walk the walk and figure things out on your own at the end of the day.
