I disagree with the law of gravity, myself.

If it works for you, fine. It certainly isn't something we should ever
encourage. Lots of stuff breaks -- calibrated loops, applications that
make use of specific instructions that aren't in both processors,
etc. If you want to do it, fine, but I don't want anyone wasting time
making support better for a bad idea.

No, we're a volunteer project, and we are happy to include whatever
support is provided. There is a big difference.
