i'm not entirely sure how *hyph*.tex files are transported into patterns
in formats, nowadays; the old system has certainly changed, since the
patterns are also generated for the utf-8-based engines, but how
precisely this happens, and how it might affect your example, ...

someone from the hyphenation working group may be along soon.

[btw, someone mentioned that the pattern file for uk english may have
been replaced, yet your evidence is that it hasn't...  the non-freeness
of the original derived from the oxford university press' insistence on
no change to the patterns, which were derived from oup files.]
