That's the focus of the second (upcoming) article :)

Minor correction: CLAP was not made by U-he, but by someone who works for Bitwig and maintains VST2 builds of U-he synths for Linux.

Schwaa has basic support of CLAP in Reaper at the very least in his own branch. I believe both Reaper and Bitwig devs are waiting for CLAP 1.0 to be announced to make all this official. Which is not too far away.
