I’m not aware of any planned change in this space. The best thing to do here is to create a small test project that illustrates the issue (working on iOS 12, failing on iOS 13 beta) and then file a bugbug report with that project attached.
As part of this you’ll need to include a sysdiagnose log. Before taking that log, install both the CFNetwork for iOS and Network Diagnostics for iOS profiles. See our Bug Reporting > Profiles and Logs page for details.
Post your bug number, just for the record.

I've attached a sysdiagnose log to FB7045254.
Thank you, Quinn!
I've filed a bug report, its number is: FB7045254.
The only thing is that I wasn't able to attach a sysdiagnose log, because I'm currenly don't have a "physical" iOS device capabable of iOS 13. I'll try to ask my colleagues to collect the logs.
