Sadly, your commonly held belief is wrong (imho) -- p
values/statistical significance are not a legitimate decision criteria
for model "appropriateness," especially scientific appropriateness.
That requires more careful consideration of a relevant "utility
function" (to use Frank Harrell's phrase), effect sizes, power, etc.,
a more detailed discussion of which belongs elsewhere, not here, as
this has nothing to do with R.
For that reason, anyone with a contrary opinion on this -- there may
be many who disagree -- should reply personally offlist.
