The page specifically says that it's suitable for modding support, and both documentation and the itch demo showcase dynamic loading, so yes
Mac OS X & Linux support, name change
The extension now has Mac and Linux versions.
Linux version works "out-of-box" (same as Windows version).
Mac version may require tinkering depending on GMS version.
Name was changed from "LUAGaMoLe" to "Apollo", since the first pun was a bit too hard to get (and too hard to memorize as a name).
