In my opinion the functionality is useful.

Agreed. I propose to integrate this functionality into the SRE syntax,
so that this special kind of group may be used when explicitly wanted.
This would avoid backward compatibility problems, would give each
regular expression a single meaning, and would allow interleaving
hierarchical/non-hierarchical groups.

I offer myself to integrate the change once we decide on the right
way to implement it, and achieve consensus on its adoption.

Best regards,
