I don't think it's right to keep adding ! everywhere.
If you are refactoring, then it should follow the best practice and make the code readable / maintainable -- unless you will do quick following up changes to fix them in short time.
Just like the "jQuery removal", adding a lot ? only makes code difficult to read or maintain. At last I have to clean up them one by one to really finish the refactoring.
For this one, maybe the proper fix is to use useTemplateRef<T>
And a lot of other places also need a proper fix.

Yes, it is better to try to ensure stuff is non-nullable in first place, I will see what I can do, but some stuff like DOM queries are unfixable without major refactors that adds ifs everywhere and I think I will defer that to later and keep the !.

A big step towards enabling strict mode in Typescript.
There was definitely a good share of potential bugs while refactoring this. When in doubt, I opted to keep the potentially broken behaviour. Notably, the
DOMEventtype is gone, it was broken and we're better of with type assertions one.target.
