Having had no issues with them sounds unreal.

Everyone has to learn what they can do and what to avoid.

We use the to build our whole system out of one commit, although we have several repos. We made the artificial rule that a commit that updates a submodule must not contain any other changes. It has reduced the number of problems especially related to rebasing.

I had no issues that were directly attributable to the way they behave and not to my own ignorance.

In short: once I learned and documented the checkout/update/reset commands, I was set.

The other “issues” were that they require extra config in some cases (CI), but again it’s just 2 lines in most cases.

I don't trust GP, I deal with them every day and they are a nuisance every day. Perhaps they are not working in these submodules and just set them to a hash once and never had to make changes there. Then sure, but as soon as you're working actively in these submodules it's mayhem.
