Could you clear up for me what "currently" means in this context? I
don't know what code was changed in January or so -- only that the
change led to incorrect reports, on a Thinkpad T400s with two
batteries inserted.

I am not sure what that means, concretely.
Is this what you mean by "proper" support,
Proper support means at least giving a good estimate for how long
before the machine runs out of energy, and a good estimate of the
actual fraction of maximum charge the batteries can hold. The code
from last October could do that.
When I type M-x battery in the version as of October 2,
it displays something like
Power BAT, battery Discharging (98.1% load, remaining time 4:04)
where the numbers depend on the energy capacity of each battery and
the current charge of each battery, as well as the actual current or
power.
That is what I think is crucial for M-x battery.
