As I understand it, base-files contains the file
/etc/defaults/etc/skel/.bash_profile.
At installation, /etc/postinstall/base-files.sh copies that to
/etc/skel/.bash_profile, if it that file doesn't exist already.
Then at uninstall, if /etc/preremove/base-files.sh finds that
/etc/skel/.bash_profile is not changed, it is removed (so that
an updated package feels free to copy over the new version).

Further, when a user *first* logs in, /etc/skel/.bash_profile
is copied to ~/.bash_profile by the /etc/profile script.  At no
other point are files in ~ modified, as I understand it.  The
way I read your explanation above, you are implying that your
~/.bash_profile is updated along with /etc/skel/.bash_profile,
and I simply fail to see where that is happening.  It is also
counter to the message from /etc/profile (also quoted by Mike):

  Copying skeleton files.
  These files are for the users to personalise their cygwin experience.

  They will never be overwritten nor automatically updated.

I.e. my /etc/skel/.bash_profile is version 4.0-9 as I expect,
but my ~/.bash_profile is the old 4.0-6 version from when I
first logged in, and I see no code anywhere that checks if
~/.bash_profile matches /etc/skel/.bash_profile and updates
if it is pristine.  So, the question remains, why is your
~/.bash_profile updated when you upgrade the base-files package?

Or have I misinterpreted your message again?

.bash_profile is of course just an example in this, select any
of .bash_profile, .inputrc, .bashrc and .profile.

Cheers,
Peter
