That is somewhat orthogonal to my point of "'some uses' of the 20 year old S4
system (which as we know is fairly widely used 'out there') break
deployments" and the related "this is also a PITA for binary distributors".

The existing body of code seems to need some help.

I haven't followed the S7 repo closely but peek every couple of months. It
seems sensible to avoid repeating shortcomings identfied elsewhere.

Best,  Dirk
