If rengar revert is not happening, can we add these 2 simple things that old rengar had?

Old rengar before assassin rework was able to ult then use tp and when tp was finished he would still be in stealth and have a gap closer. The new rengar does not have this perk, if you use ult then tp, the tp will cancel your ult. It would kinda be nice, and make rengar top have more options than flash exhaust in every game. Second thing is that rengar's ult cancels when you use sweepers... I dont see why that happens its really harmless and doesnt really harm anyone.
