legendLayersAdded signal not fired anymore in master?

[rduivenvoorde]

What is the bug or the crash?

Hi, having a plugin which uses the legendLayersAdded signal:
https://qgis.org/pyqgis/master/core/QgsProject.html?#qgis.core.QgsProject.legendLayersAdded

I found that current master (only) it is not fired anymore (while in 3.28 and older it is)

Steps to reproduce the issue

• open QGIS
• open Python console
• run following lines of code

QgsProject.instance().legendLayersAdded.connect(lambda: print('legendLayersAdded fired'))
QgsProject.instance().layerWasAdded.connect(lambda: print('layerWasAdded fired'))

Now drag/drop a shpfile/geojson whatever onto the mapcanvas.

In 3.28 I see:

layerWasAdded fired
legendLayersAdded fired

but in master only:

layerWasAdded fired

Anybody can confirm?

Ok, after some trial and error with recent commit, I think this commit 43d9fac accidently removed the signal.
Or at least, compiling that commit it is gone :-)

@nirvn is it possible that we dropped the signal somewhere? Cannot see something removed, but maybe it should be fired again somewhere?
