No way to disable the animations without warnings

[galanovnick]

Description

The exit or entry animations can't be omitted without warning messages.
Would be really nice to have a property noAnimation or something like that.

Expected outcome

No warnings present when exit, entry or both of the animations are omitted.

Actual outcome

Warnings are popped up in the console.
