flyspell overlays removed in comments: does this make sense?

[Eric S Fraga <e.fraga@ucl.ac.uk>]

Hello all,

for some time (years, really), I've suffered with flyspell overlays
disappearing in comments in org documents.  It never occurred to me that
this was due to org itself so I just put up with and chalked it up to
one of those Emacs mysteries.  Today, for unrelated reasons [1], I ended
up looking at the code, specifically

org-fontify-meta-lines-and-blocks-1

and see that org explicitly removes flyspell overlays in comments.

Before I look into maybe adding a user option for the flyspell issue,
can somebody explain the rationale for this?  My comments tend to be
natural languages so flyspell is most definitely useful.  Okay, spelling
errors in comments may matter less in terms of dissemination but
still...

Or have I misunderstood something fundamental?

thank you,
eric


Footnotes:

[1] The unrelated reason is that I was looking at how I could get my own
user-defined meta lines ("#+calc: " for my use of embedded calc in org,
for the curious amongst you) fontified the way I want them.  Not easy,
as far as I can see.  I further noticed that org also removes flyspell
overlays from any "other" meta line, i.e. any other meta line not
processed by specific code.
