One usecase is perhaps to save space if using trampoline anyway...
more importantly, if using gossip, LNGossip is heavily filtering what messages we request and get,
and e.g. can missing new NodeAnnouncements, etc,
and this is a quick-and-dirty workaround to force a fresh start.
kivy 2.1 seemingly became more sensitive to threading issues.
This used to work on kivy 2.0 and older, but 2.1 is complaining.

- Do not send ping if messages have been received recently.
- Do not send more than one ping.
- Await pong before sending commitment_signed (per BOLT-2)
- Lower ping time to 30s
closes https://github.com/spesmilo/electrum/issues/4072
(this fix AFAICT only works on Windows, and #4072 contains some macOS reports as well,
however all recent reports are for Windows and overall most reports are for Windows,
so let's close it optimistically for now)
protobuf 4.x introduced breaking changes compared to 3.20.
To adapt, we would have to regenerate paymentrequest_pb2.py, using protoc>=3.19.0, however ubuntu does not have new enough protoc.
Also, unsure if newly generated paymentrequest_pb2.py would be supported by older versions of protobuf.
Best to just wait for things to settle.

E If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
E If you cannot immediately regenerate your protos, some other possible workarounds are:
E 1. Downgrade the protobuf package to 3.20.x or lower.
E 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
