Whether time really exists or not, thus far "winding the clock back" is something I have yet to experience. So any time spent may as well have been worthwhile.
Hence, when evaluating the prospects of a potential solution, spend time wisely by getting a meaningful "wall-to-wall" overview and "feel" of the entirety from inception through to its logical conclusion before getting down to brass tacks i.e. the details.
Once deemed worthwhile as a whole and high level due diligence having been carried out, only then should the more detailed issues be attended to (e.g. the particular advantage of a feature, etc.).
If eventually deemed without meaningful value, minimal time will have been spent and therefore wasted.
