For example

mux := asynq.NewServeMux()
mux.Handle("sendemail", newHandler())

Modified code

mux := asynq.NewServeMux()
mux.Handle("sendsms", newHandler())

I have registered MUX Handler sendemail, but if the MUX Handler method is deleted, Not Found for Task sendemail will appear after starting next time

Hi @tocomp,
if the MUX Handler method is deleted, Not Found for Task sendemail will appear after starting next time
Can you give me exactly your expectations for this use case?
As I know, per task type should have a particular handler. So, for your case, I suggest you should clear old data via some
solutions below:

Set Empty logic handler for sendemail type. Always return error = nil.
Clear data from [asynmon](https://github.com/hibiken/asynqmon)
