That's a test scenario and you're not supposed to use that anyway. Use configuration examples from here: https://wiki.strongswan.org/projects/strongswan/wiki/UsableExamples

Look at https://wiki.strongswan.org/projects/strongswan/wiki/UsableExamples#Host-To-Host-transport-mode
TL;DR: Use rightsubnet instead of right. Don't set right.

All else being equal, I'd rather be in the mainstream so I can use other people's known-good configs as a reference point. Is the intent to eventually deprecate ipsec.conf in favor of swanctl, or is swanctl just an alternative?

ipsec.conf will coexist with swanctl and it will be eventually (maybe in some years) removed. Right now, swanctl is a (more powerful and better) alternative to ipsec.conf

Kind regards,
