Subject: Delete gitlink entry but keep .gitmodules file unmodified
Message-ID: <4F8EBF5D.5070301@tmatesoft.com>

Suppose one has a properly initialized submodule in a tree like this:

$ git ls-tree HEAD
100644 blob d208248ba4ab1d1791dc27f451dcaedb87dc19e1	.gitmodules
160000 commit ec633ea81e3cf64c3735ef4acd5ff9a490ed54eb	ext
100644 blob 597d6924118c00054efd526d9e48f68198f7da12	file.txt

$ git show HEAD:.gitmodules
[submodule "ext"]
         path = ext
         url = $URL

Then one pulls a modification that replaces 'ext' gitlink by some blob 
or tree entry, but keeps '.gitmodules' the same:

$ git ls-tree HEAD
100644 blob d208248ba4ab1d1791dc27f451dcaedb87dc19e1	.gitmodules
040000 tree 82e3a754b6a0fcb238b03c0e47d05219fbf9cf89	ext
100644 blob 597d6924118c00054efd526d9e48f68198f7da12	file.txt

Are there any possible downsides of such modification we should be aware of?

Thanks,
