Every device you add between you and your ISP decreases reliability, increases latency and increases your attack surface. Remote management should be opt in. This is one of those "smart" ideas, that I imagine it was thought up by some guy who previously worked for a company IT department before cloud computing made him redundant. They trained him about restricting access to everything "for the greater good" and now he wants to bring these "advanced" concepts to "those most in need".
I trust 3rd party device so little that I'm pretty much on a fiber to ethernet converter (hardware converter, just plain hardware, not software based), straight into PFSense. Net effect is I never reboot, never have problems unless the ISP broke something. For me uptime matters. For another customer other things matter, just give the customer what they want.
Replace that with some cheap router that only you can run and you have endless problems for power users and your non-power users still call in all the time with problems. The first problem was that you bought cheap routers and your end mile installation sucks and gets damaged all the time
You can't fix that by squeezing your customers into your corporate management mindset ¯\_(ツ)_/¯
