As per the iFixit report, the Apple chip that identifies it as an 'Apple Battery' can be moved to another battery from any/dubious source. Given this, how can software KNOW that it's truly an Apple original battery.
Therefore, Apple is only 'vouching' for the battery health of batteries replaced via a confirmed 'chain-of-custody'.
Could the message allow the health to be shown anyway? Sure... but it's not like a message pops up every time you wake your phone.

Doesn't that work against your argument? If you put in the effort to move the chip, the phone will never know you replaced the battery at all.
It's no riskier to trust the chip post-replacement than it is to trust the chip any other day of the year.
