Dear julienc30593385,
Tricky question. Is there any stopper for it? Don't think so.
s.t() or s.tl() both can use Variables configured or set using Plugins. If you add Plugins to your Base Code, you can use it either on s.t() or s.tl() because you wont be using the plugin directly rather the variables set using the plugins.
Thank You!
Arun
