Sorry, but, as FPC maintaining team member, I don't share this __ should __
statement for the following reasons.
 * GTK2 is declared as deprecated in Debian since long time ago.
 * Technically, Lazarus doe snot need libgtk2.0-dev for running, and thus should
   not pull it.
 * Technically, FPC does not need any GTK related lib, it only provide binding
   units. So it should not pull it either.
 * For building, Lazarus build depends on libgtk2.0-dev, until it will migrate
   to gtk3. And so shall do all programs that use it.

I hope this makes it clear, why neither Lazarus, nor FPC or any of their
packages should pull libgtk2.0-dev package.
You should handle this bug in VMG, and probably the best way to do it is to
build depend on libgtk-2.0-dev until you
fix https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=967798
