Thank you for these hints, which moreover remember me the persistent case folding
issue around the LATIN CAPITAL LETTER SHARP S which is not round-trip neither
and needs to be tailored, because its small letter is to be kept stable.
Seen from here, tailoring the Greek small theta to get it the Latin way around
becomes quite obvious:

Without tailoring:
ẞ ⇒ ß ⇒ SS
ϴ ⇒ θ ⇒ Θ

With tailoring:
ẞ ⇒ ß ⇒ ẞ
ϴ ⇒ θ ⇒ ϴ

Now I’m much likely to believe that theta-using Latin script writers are eventually
better served with the UTCʼs not retaining a separate Latin theta, because
tailoring this custom Greek casing pair presumably makes for a more streamlined
implementation and a more user-friendly result, given that the font issue is
spared. The more as for units like Ohm and prefixes like micro, Greek letters are
preferred too, no matter what script they are used in.

But it is, since the thread was about IPA, so uppercase was not discussed.]

The question still remains whether in practice this working model could be
unanimously accepted, given that at least somebody is preferring the regular
Greek capital, presumably to get around the case folding issue.
