The "if you break it, you get to keep the pieces" saying comes to mind
as we do not promise anywhere that testthat is in fact supported ...

Stricly personally speaking, I have always found devtools and testthat
too obfuscating for my liking.  I build much smaller, simpler tools
around littler. That works for me. And for unit tests, I still rely on
RUnit.  But that is just my view.

If someone wants to work on (additonal, optional) support for
testthat etc, the doors are always open for good pull requests.
