Not entirely.  For example, Eclipse/CDT implements a mapping.
That allow folks to "map" paths to a different value.

The source lookup is not done by gdb, when the editor comes highlighting
the line,  The IDE has a list of paths it has to search.
It is/was not that important to set gdb's directory sources.

Agreed, we have folks using the CDT having > 10 000 files, source lookup
is a pain.  Having the fullPath is a definitive plus, even if we do
processing like respecting the paths order and mapping.
