I think this mainly depends on the overall impact of the modifications.
Quoting from the original post

I at least would like to know the performance impact of the modifications in
particular for those (probably 99.9%) of the cases where the return should
not be caught by a termination handler.

Since there are other alternatives (such as fixing block return to search
the entire sender chain before attempting to return) I would really like to
see a few numbers first.
