By spec all wifi devices should be able to detect they have been dropped and ask to re-associate.
Home routers have limited resources and limited number of clients (some hardware is capped at 32 clients max).
That said, for hostapd (the application that is using this config to operate the wifi in the device) this option is default 0

while in OpenWrt this is set to 1 by default
from this commit done in the old source archive https://git.openwrt.org/?p=openwrt/svn-archive/openwrt.git;a=commit;h=9b020e776ec7fb475b38ef3403ff5c88e523fe93
hostapd: enable disassoc on many consecutive excessive retries, improves AP mode reliability with many clients
I think that it can be a good idea to open a PR on github or on mailing list to change this default, they either accept it or reject it and tell you a better answer than a couple lines from the old commit.
