Bootloader unlocking is possible on international model Samsung devices

  You're correct! Thanks for that information. My Samsung Galaxy A51
SM-A515F (SM-A515FZKVEUB to be precise), bought in The Netherlands,
indeed has that option.

 
Lucky you! I wonder if any international models would even work in the
US - this has been added to my research agenda, though it's probably
going to stay low on the priority list until my phone installment plan
is paid off...

  Before bying this particular model, I studied the needed/available
(2G/3G/4G) frequency bands in detail, because I needed to use the phone
in EU countries in Europe and in Australia. Australia's main provider
(Telstra) with the widest coverage, uses some quite 'special' frequency
bands (to get that wide coverage), so I had to be sure my phone had
those bands.

  Most webshops did not give those details, but my main webshop
mentioned the exact/full product numbers and Samsung was one of the few
brands which mentioned these exact product numbers. So I could look at
the webshop site for a candidate and then lookup its frequence bands on
the (Dutch) Samsung site.

  FYI, not that it is of much help, because my phone is already a few
years old, but my phone (see above) *does* work in the US. Tested on my
2023 trip to the Indy 500 (Chicago to Indianapolis and back).

This is a good point, and I agree with you to quite some extent.
However, I still think the option should be available - and could be
made available - for those who "know what they're doing".

  I've seen many posts from users complaining about not being able to
unlock the bootloader, who did not seem to know/realize the
consequences. But as long *you* know what you're doing, all is fine! :-)

 
The more I know about what I'm doing, the less I feel like I know
what I'm doing at all...Dunning and Kruger would like a word
 

I also certainly would not trust any of these services.

Now I'm very curious what your use case was for this!

  The Android version (of my stone-age Huawei Ascend Y300 phone) was too
old (4.1.1) to be usable (and it was too small (4GB Internal Storage)).
So I wanted to use it as a guinea pig to try to install a 'new' version
of LineageOS, with the intention to then install LineageOS on my
slightly newer/better (then-)current phone. But during the process the
current phone kicked the bucket, so I had a useless phone and a dead
phone, so I bought the Samsung A51. Some technical problems can be solved
by money! :-)
