You are right, I did not check R devel.

You probably misunderstood what I wanted to say.

It is clear to me that you are doing a great job distributing thousands 
of package binaries. No one does know it better than me with the special 
problems you have to build binaries for xps. I really appreciate that 
during all these years you and Dan (and others) managed to support xps 
like all other BioC packages.

I meant that from the user standpoint it probably does not matter much 
which of these three systems are used to build BioC, in contrast to Sierra.

But as you said below backward-compatibility is always lost, so the 
question which system to use to build R/BioC is always tricky. Maybe, 
the best (?) decision would be to use the system which most Mac users 
are currently using, but I don't know.

Best regards,
Christian
