I think this stance of EAM isn't and will never be enforced.
They just made that list of approved games so they don't need to keep downloading and testing every single 3rd party app to UO do define what's legal and what's not.
They won't be running around checking if players are using certain programs.
UOPro died, and frankly there aren't many 3rd party programs beeing developed to UO anymore. A small effort to test the most used programs and make an updated list, and some useful guidlines of what is actually valid...

Hell, you could make unnatended macro without even using a UO-specific tool..
There's a program called UO Auto-Pilot, that let you script a macro...
The thing is, it does not interfere with the data packets or anything, it just automatically moves the mouse around, doing what you would do...
There are MANY macro programs for desktop applications that would do the same thing...
So there it is, macroing without a UO tool...
Also, really hard to believe that something like UOLoop would be illegal...
UOLoop simply keeps repeating the same keystroke, to use a macro you made in UO, so you don't have to press ctrl+f1 hundreds of time to train arms lore.
And there are many desktop programs that would do that.

I use Razor, that is just like UOA, but free to use... Doesn't give me any advantage UOA wouldn't give me (auto picking regs from ground, opening corpses, etc), and I don't even use those things...
I use it for recording macros for training.
There isn't a single thing I do in UO that is illegal, and using an app EAM refuses to test is my only "crime"
