do you mean removing the ip-check and consider email with IP as valid?

no problem. We can add proper validation for URL after split in a 
validation class. As filter comes with a huge constants-setting, also 
combinable, i see no problem to have such wrappers for more easy usage. 
Otherwise we could say the same for some other strpos/str_replace 
wrappers we already have :-)
