[Talk-us] Highway shield rendering: What's the blocker?

[Richard Weait]

if I remember correctly, the US Local Chapter was planning to render
highway shields, now that combined shield and overlap rendering is
solved.

What happened to that?  Is there a blocker?  If so, what is / are the
blocker(s)?

There appears to be periodic community interest in highway shields.
Who is still interested in advancing this?
