I guess that when I made the script it wasn't available. Anyway, I look
at it when I have time (probably when Tomas, his students and I also
look into (new) patterns for (newly) supported languages).
I don't understand the "really bad" because I can't remember any context
user bothering about it (nowadays changes in fonts and handling of
features are more influential). Also, we currently ship only the
versions of patterns that Arthur and Mojca consider to be okay (the last
ones). Users can easily freeze a system that they need for a specific
long term stable situation. I'm pretty sure that when patterns improve
users are happy to check their document rendering (tex often doesn't
hyphenate that much anyway) and never check the files related to
patterns (so no one would notice a version number).
So, I'll add it to the stack of todo's, but with low priority,

Subject: version data missing in ConTeXt hyphenation patterns
[Since I'm not sure who is responsible for generating the pattern
files for ConTeXt I'm writing to this list.]
If I look into file
tex/context/patterns/mkiv/lang-de.lua
I see the following.
["metadata"]={
["mnemonic"]="de",
["source"]="hyph-de-1996",
["texcomment"]="% no comment",
}
However, version information is completely missing. For example, file
tex/generic/hyph-utf8/patterns/tex/hyph-de-1996.tex
contains
% version: 2019-04-04
[Arthur worked hard to make the comment format uniform for all
pattern files in `hyph-utf8`!]
This omission is really bad IMHO, since the version of the patterns
are essential to get identical line breaks for older documents.
I guess it shouldn't be too difficiult to update the `mtxrun` script,
making it add
["version"]="2019-04-04"
to the 'metadata' block. Or maybe it's better to make it update the
`.rme` files with the corresponding information.
