You are misinterpreting that, so no, it's not an atmosphere issue.The part about it being about desynced battery metrics or a modchip was uncalled for, as if there hadn't been well-known battery-draining issues that have nothing to do with hardware.
And the part about it not being an atmosphere issue is debatable, it doesn't seem like adding those lines from Github cause any issues at all so they could actually be added by default, putting this issue to rest once and for all.
the "lines" you speak of are a concept of set-mitm, which overrides the values applicable from https://switchbrew.org/wiki/System_Settings
and no, the values you speak of should not ever be default, as atmosphere is designed to be used while connected to nintendo, while being able to access eshop, while being able to play online and while being able to pay for games. The usecase where that doesn't happen, and the user profile de-syncs, is in 90% a piracy related problem.
(enable_sync_elicense_request = 0x0 <----- anti-piracy check within NS (the module that does rights management on the switch, specific to digital temporary licenses, gained from nintendo switch online, ex: "free" animal crossing dlc, if one chooses to not buy the dlc, but gains it from NSO, moment NSO runs out, the elicense will revoke itself and the dlc will become deactivated))
