Oh, i never tried this feature, sure it's a lot more useful than the autoswitch when Monero forks (twice a year). I'm still not confident to have time enough to implement it, but you convinced me it's not just a gadget feature 
I hope i'll be able to release the v8-capable CPU version soon.

Moneroocean pool also uses XMrig for algo switching, it's really useful and gives nice profits.
XMR Stack can also be compiled to use algo switch, and SRB also supports it.
Just sayin', so you don't get left behind
While i do agree with you and think that auto algo switch is a good idea and can create better profits, i also think that the way is currently implemented in other miners is very trivial and thus i refused to use it. The fact that you need to manually configure and test every algo is wasting time in my opinion. Another waste of time is that in the current trivial implementation, the miner has to restart when changing the algo.
What i really hope is that in the future more altcoins will implement algos that are very compatible with what Monero is putting out there and that due to this, miner software can be modified to perform an auto algo switch as fast as they do the devfee switch.
At this point i find the current implementation of algo switch more of an interruption to mining with very small increase in profits.
