perhaps a stupid question: Isn't it possible to simply make bigger pads on
the board and spend more soldering paste on them? The used MMCX connector
itself seems completely ok for me, but its connections to the board are
definitely too weak.

Currently I can confirm that it's indeed very easy to break them... :-(
If you know a manufacturer of such a connector that has the right height
above the PCB and is surface mountable... The one we use was the best and
only one we could get hands on.
Am I right that it's hardly possible to reconnect an MMCX socket that has
lost its connections to the board?
Well, it is possible. But needs a good microscope, a very thin wire, a
very calm hand and a lot of patience...
Another question on external antenna:
I see that "cat /sys/class/regulator/regulator.8/microvolts" shows 2.8V
but I cannot find gpio144 and gpio145 any more within
"/sys/devices/virtual/gpio". It's also not possible to get them within
"/sys/class/gpio". Where have these both gpios been moved to?
I was also wondering recently. I think they are missing in the 3.x
