Yes and no.

Application sandboxing is not a need I have or one that I want my display manager to solve.

But incompatibility vs the architecture disallows features like screen sharing, automation or accessibility means I will not ever have it installed anywhere.

I can't tell people want to do, but those features seem very "contemporary" to me.

Perhaps it's because I use linux as my work desktop. I suppose if this is the feature I should just migrate to OSX.

Because I need video conferencing. I don't need a sandbox. I already am selective about what I install and most of those things aren't even desktop applications.
