Not always: working on a problem, the solution may come later on, while
walking, dreaming etc. So, the circumstance in which you find a sequence is
interesting but doesn't say about the "contriveness".
BTW, I think certain types of contriveness ("to sit down etc") are ok when
they lead to new ideas, instead of other numeric variations on a fixed idea.

If you arrive to an existing sequence, coming from an entirely different
point of view, this is interesting. And may give an interesting comment to
the existing sequence.

Yes ...and again your reasoning to rediscover it. (then again a Comment may
be worth to be added. Ex: A000217, triangular numbers: a dozen and a half
*different* ways to come to this sequence.)
