At a prior job (fairly recently, past ~5 years), we still used ColdFusion MX7 for some internal apps and reports. They had been around for a long time, so don't break what works I suppose. :)
The biggest issue with them was that _some_ feature (cfform IIRC) was generating flash .swf input forms, which broke after the flash player EOL. Switching it directly to the plain html version wasn't compatible, so we had to manually fix a bunch of code.
