return value of L.Handler.addTo()

[johnd0e]

Is your feature request related to a problem? Please describe.

There is static function which can be called without instantiating L.Handler
addTo(<Map> map, <String> name)

Returns: this

This method return class, not instance.
I could be wrong, but I can make the only use case: add same handler to several maps at once, like myHandler.addTo(map1,'someHandler').addTo(map2,'someHandler').addTo(map3,'someHandler');
Not very useful, IMHO.

Describe the solution you'd like
I suppose that more useful would be to return instance here, to be able to call later it's methods:

var handlerInstance = `myHandler.addTo(map,'someHandler');

Describe alternatives you've considered

map.addHandler('someHandler', myHandler);
var handlerInstance = map.someHandler;

This works, but a bit ugly.
