Just to jump in here, there is one use case for a lightweight DE that
doesn't involve obsolete hardware: multiuser mainframe-type systems.  When
you have 50 users on one central server, each with a session that is being
accessed via a remote desktop protocol such as VNC or even the X
protocols, slight reductions in the overhead of each session make a big
difference overall.

Just something to think about in these odd times, when the personal
computer is being "replaced" with a variant of the old central mainframe
