I got ya.. I figure we still seem to value everything and do commerce based on the fiat dollar, so those fractionals aren't front and center

As far as Bitcoin's code is concerned, there are no decimals. Sats are the base unit on the blockchain.

The concept that 100,000,000 sats = 1 Bitcoin is a social agreement external to the actual way Bitcoin works.

That said, it is such a longstanding social agreement that it would absolutely cause a lot of confusion and controversy to try and change it now.

Keep the 1 Bitcoin = 100,000,000 sats for the sake of consistency. To change it at this point would make a whole lot of folks scream "I thought Bitcoin didn't have inflation!" because no one actually knows how division works...
