Dear Maintainer,

I have been using my own systemd.service and systemd.slice's to run vnc sessions with resource control until I recently became aware that there is a tigervncsesson@.service that can be used instead.
As far as I can tell there is no (out of the box) method to tie a systemd.slice to a vncserver.user for resource control.
For example "Fred" and "Barney" might need lower CPU weight than "Wilma".
(I must admit that I have not tested if applying a simple pr. user resource control as described in man systemd.resource-control would suffice)
