Apologies. This was not intended.

Just the bigger picture: We do bioinformatics, which includes the
tasks of creating, processing, storing, copying, moving, backup and
restoring sparse files.
Until now (before Cygwin added sparse file support, for which I am
VERY GRATEFUL!!) doing this on Windows was a serious PAIN, causing
many problems, which all ended up on my radar.

What we decided last year is to try and fix the WHOLE situation from
beginning (file creation) over middle (copy, move, transfer,
filtering) to the end (backup, destore, delete), and do that for every
IT provider and operating system as needed.
I even decided to get my own hands dirty, get GE HealthCare
(ex-Amersham), NIH, IBM+Oracle (IT providers) and the involved
universities all into the boat, and FIX sparse file bugs. CERN, NIH,
DESY and Oracle Linux staff also joined the fray.

That is lots of work, with many meetings, and not every software
vendor is keen to mop up issues.
Let alone Microsoft needed 3 years to add /sparse to xcopy, and only
did that in a way which requires the latest Win11 version; the
powershell sparse file bugs are still all in limbo. Thus I am happy
that Cygwin has now support to copy, move and backup sparse files in a
RELIABLE and Windows-version independent manner.

Sign, I didn't start that one.
But I apologize and agree I shouldn't mix management behaviour towards
half-unwilling commercial entities with open source projects.

cygutils-extra

Is it wise to put a simple utility in a separate package?

That I am doing right now. Mostly by testing/collecting bug reports,
scheduling meetings, and getting software vendors to fix their bugs,
but I honestly do not contribute much code. I barely have enough time
to deal with commercial software vendors to fix their sparse file
bugs, on top of my normal duties.
But yes, I will try harder in the future.
