We do it all the time and never had any problem. Of course you have to comply with minumum attenuation requirements (don't test them with a short patch, you could damage your receivers).

I too am curious to hear about stories of such incompatibilities, if any.

The lack of a standard means that if it actually doesn't work, you will have a hard time to blame it on vendors. I'm afraid you have to accept this risk.
