I trust you guys have considered the implications of these forbidden groups, but it's worth noting that an inability to converge a proper geometry doesn't mean a structure couldn't be an intermediate in a concerted reaction RMG takes multiple steps to do.

I haven't thought about that. Does it hold even if I define a forbidden Species and not a Group?

Forbidden species would be less risky because they only apply to that one species. The issue isn't that common, but it is worth considering as forbidding a pathway that's real could be a huge problem for someone later on.
