I am slowly moving custom to specifiers, but it isn't that easy
I know how you feel -- I tried to do that, and I gave up.
2. Specifier tags for _all_ domains. Customize uses 'dark and
tags to have different color sets for different backgrounds. There
must be some way to turn those into specifier tags. The current
solution is a cop-out (basically emulating FSF frame-properties)
but a perfect solution would be dynamic and work per window.
Note that it would be possible to compatibly add new specifier tags
for all domains, e.g. by a new DOMAINS optional argument to
`define-specifier-tag', or by a new function
However, the problem is that the current specifier implementation has
to be extended to support such on-the-fly fetching of relevant data.
I believe Kirill did some work on this, but it was never finished.
