I oppose, this way lies madness.

Ether a shellscript is POSIX compliant, and works on all POSIX
compliant shells, or it's not, then you are free to do
#!/bin/bash or whatever, but don't rely on a nonstandard feature
being present in other shells as well. Just testing some shells
is _no_ substitute for standard compliance.
