It is.  It's expensive, and needs lots of power and lots of cooling, so
you don't see it in workstations except for a chip or two to drive
monochrome hi-res video systems.  In large servers and mainframes it is
not uncommon.

(As John Mashey has commented, a desktop ECL box would need no desk space,
because it could hover above the desk on its cooling fans.)
