For the sake of portability I had to do a quick due diligence
for non-GNU grep implementations.
Based on on-line manpages, "grep -E" support has been common for
some 15+ years in non-GNU implementations. It's in IEEE Std
1003.1-2008, maybe earlier, and appears to be adopted globally.
I'll start with adopting this into the Postfix 3.8 development cycle.
