I don't claim that it's not useful and the bug report was not aiming to
get rid of dlocate... but to tell you that you should update your code
to use the proper interfaces and not to access internal files.
So please don't reassign it to dpkg, that doesn't make sense.

So you can certainly concatenate the output of "dpkg -L <package>"
executed on all packages ?
For better performances you can give multiple parameters to "dpkg -L".
The tricky part (if you want to be compatible to multiarch) is to get
the list of all packages...
dpkg-query -f'${binary:Package} ${Package}\n' -W|awk '{print $1}' should
do it. With a multiarch dpkg, ${binary:Package} will be non-empty and
thus used. For older dpkg, the usual ${Package} substitution will be used.

Why wouldn't "dpkg -L" be enough ?
