I may be missing something, but the results of lm just give you a
p-value and then you are in charge of setting a significance level.
And as for hypothesis testing- like t-tests you are also in charge of
the significance level.  Am I missing something?

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
