Considering the low end, the batteries are so poor and have such

designed with all of the electronics necessary to correctly charge the
batteries and preserve their lifetime? Of course not.

How do you know that?

I suspect that with the advent of cheap, single chip, fast charger ICs
it's just as cheap, if not cheaper to provide a proper, 'intelligent'
fast charger as it is to supply a 'unintelligent' one.

I'm almost tempted to take apart the charger from my cheapo, generic,
cordless lopper to see if it does have an intelligent charger. It
certainly acts like it has one.
