The python modules gui and core are exported and the "iface" variable
(QgisInterface) knows about their presence. But QgisInterface should
not have any dependencies on plugin code, therefore it's harder to
access this code.
It may not be hard if you only make use of code which you use in a
standalone library way (maybe that would already be enough for your
case). If you want to get access to a running plugin instance this is a
different story. You can have a look at the code in [1] for an example
of how this might be accomplished. Although the code seems not to be
working, I've got to check what's still missing there, but in principle
the ideas in commit [1] should work.
Best,
Matthias

It will not be so easy to just write wrappers because the code is not
exported to the gui or core libraries/sip modules.
I have written code that makes it possible to generate python
bindings for (C++) plugins and I'm considering creating a
pull-request for it.

It depends on what parts of the Georeferencer you need. If you don't
need the GUI but only the math, you could consider writing a SIP
wrapper around QgsGeorefTransformInterface implementations [1].
Otherwise, if Python performance would suffice, you could grab the
low level math from QgsGeorefTransform and QgsLeastSquares [2] and
translate it to Python.

Hello Giovanni,
thanks for your answer. Do you think it is easier to write
the Plugin for the historical border extraction in c++
instead of python, cause of the binding implementation?

Hi Felix,
I fear you will have to write your own bindings if you
want to leavarage the Georeferencer plugin code. It's a
plugin, so it's functionality isn't exposed through QGIS
API.
