Peter Brett submitted WG2 N5168
<https://www.unicode.org/wg2/docs/n5168R1-ISO10646.pdf> late last year
and the WG2 project editor followed up with WG2 N5174
<https://www.unicode.org/wg2/docs/n5174-namesaliases.pdf>; a proposal to
address the reported concerns regarding name aliases. The proposed
changes add a normative reference to NameAliases.txt and, hopefully,
clean up the presentation some.

Perhaps it would be worthwhile reaching out to the WG2 project editor to
report the difficulties you are encountering. Perhaps he would be
amenable to addressing them editorially or in a revision of WG2 N5174.
