bionade24 [1] filed an orphan request for vesc_tool-git [2]:

I, the co-maintainer did all the changes in the last 4 years. The
maintainer didn't even respond to comments and my reaction weren't
always the quickest, either. The maintainer account hasn't updated
other broken PKGBUILDs in years, so I guess the account is stale.
