Yes, however maybe they cannot be rebuild due to Conflict.  I will check that
before reporting bugs.

No, there are other package Depending on libjpeg62-dev that have

However, I am not quite sure the "|libjpeg62-dev' is a sane option.
Packages might end up being built against the wrong header files.

Well, what I suggest:
