Hi friend,
Why haven't any developers implemented newer version of ElectrumG (newer than 6-year-old 3.2.1) which fixes correct servers issue?

The old ElectrumG 3.2.1 is still set up with *.bitcoingold.org whereas the newest and uncompromised servers are widely told to be *.btgofficial.org. Just for this vital change ElectrumG deserves an update.

Thanks!
