Even if we ignore the legacy aspect, the main strength of mIRC's scripting language has always been that it lets people achieve many simple things with ease. For basic and common scripting problems such as thanking someone for opping you on a channel, "on OP" provides an easy solution, whereas "on RAWMODE" poses an insurmountable parsing challenge for a beginner. As a result, both events are valuable even if one is strictly speaking a superset of the other.
So yes, I have both a hatchback and a five-ton truck in my virtual garage. One is for getting around town, and the other is for doing heavy lifting for the few occasions where that is needed.
If you want to keep your position, you should be aware that "on PARSELINE" now covers a superset of "on RAWMODE" (and most other events), too.
