I don't think the GPS has been removed, now I would say stainless Steel is not an upgrade over titanium, the 5 Pro is for people who live a rugged lifestyle like climbing etc.
I was at the unpacked event and spoke to various Samsung managers, the classic gets upgraded every 2 years and the pro gets upgraded every 2 years, so next year the 5 pro will be upgraded and in 2025 will see a new classic. Yes you can use the lte version without an esim like a normal Bluetooth version. I hope this helps, I am torn between keeping my 5 pro or upgrading to the 6 classic, both are great.
