CFScript is a band-aid solution, it is not possible to use every CFML tag from CFScript, the implementing server has to provide a function, there is no documented way of adding top level CFScript functions, when one wants to wrap a tag in a function - good luck without having to write temporary files...
These 2 engines are not fully compatible with the official closed-source version. For example, BlueDragon handling of importing / creating instances of objects highly deviates from Adobe CF. Lucee has a whole page dedicated to unsupported tags: docs.lucee.org/reference/unsupport... and their own tags: docs.lucee.org/reference/additiona....
You're killing me dude. Your point one was correct 5 years ago. Your second point is not an issue if you know what you are doing.
You seem to have a short fuse. Even COBOL is great, if you know what you're doing.
