Thats a pretty low bar too set. in a informal context, native speakers will forgive most other grammatical mistakes as well.

I see what you did there, I think. It’s interesting: I don’t mind capitalization and the a/an substitution here, although I could see the capitalization being confusing in another context. However, it’s/its and to/too almost always take me out of the flow of the text and force me to read it again to figure out the proper meaning. As a native speaker, I would still say I forgive the mistakes, but they do undoubtedly hurt my comprehension of whatever I’m reading.

As a reader I think that distinction is more important than whether using a hyphen is correct, assuming the goal is to make oneself understood. That's all I meant.
