XDG is a freedesktop standard that's been adopted by systemd, Wayland, and other important projects. It's absolutely no skin off your nose to adopt it, and beneficial to you and your users if you do.
A systemd standard, we covered that. Great reason not to use it.

>beneficial to you and your users if you do.
Poorly thought out and imposed standards are not beneficial to anyone.
