Why not aging the BSS in use?

We are currently facing a tricky problem, we are using a WiFi chip that is sometime not so reliable and we not always receive a deauth or beacon loss from the chip when leaving the range of a network.
In such situation, we can trust that we are still connected even at kilometers from the BSS!

As a workaround we are considering to use the aging mechanism in order to not keep such BSS in the scan list.
However we saw in function "wpa_bss_update_end" in bss.c that the aging is voluntary not applied to the current BSS. 
We are wondering if is there a good reason to skip it? What could be the risk to apply aging on the BSS in use?

Any help or comment is welcome,
