However it must be clear that these aliases are case-sensitive by

said to be case-insensitive (in that case the followings are also
aliases: "arabic_pf_a", "arabic pf a"). But adding case insensitivity
has a cost, which is much higher than *only* allowing basic
replacements of spaces and underscores [...]
UAX #44 says:
5.9.2 Matching Character Names
UAX44-LM2. Ignore case, whitespace, underscore ('_'), and all medial
hyphens except the hyphen in U+1180 HANGUL JUNGSEONG O-E.
5.9.3 Matching Symbolic Values
UAX44-LM3. Ignore case, whitespace, underscore ('_'), hyphens, and any
initial prefix string "is".
I read the words "ignore case" in these two rules to mean that case
should be ignored.
