 > remove muniversal and get single-step universal building working, but that may be a much bigger undertaking.
 It was pretty easy, once I knew what was going on, to fix it for 10.15+ -- took 5 minutes.
+It was quite simple, once I knew what was going on, to fix a multiarch build for 10.15+ -- 5 minutes, as above. It becomes a 5-line build, and it builds fine with multiple arch flags if the libraries are the same depth (and does not run any binaries during configure)
 However, you will need to build it separately and lipo together for 32bit + 64bit libraries. I would have finished that off but ran into headwinds.
+However, you will need to build it twice and lipo together for 32bit + 64bit libraries. Using the muniversal PG just on older systems <10.14 would do it. The proper flag to force the library bit depth is {{{--with-library-bits=64}}} or {{{--with-library-bits=32}}}.
+Most likely using the muniversal PG just on < 10.14 would do it. And the proper flag to force 32bit libraries is a configure arg now.
+And -- personally -- I would split icu58 off into a different port, to simplify things greatly in the Portfile.
+And -- personally -- I would probably split icu58 off into it's own port, to simplify things in the Portfile, roll the docs into a variant, and get rid of {{{icu-lx}}} as is has no dependents and upstream recommends {{{harfbuzz}}} anyway.
