That's fair. This isn't a binary, and the ideal is likely somewhere in the middle.
Still, I do think there's quite a large portion of detail-planning that can be radically different dependent on the high-level expectations, even where the range of high-level outcomes is small.
i.e. (random off-the-top-of-my-head example): I'm building a piece of software offering some kind of service to end-users. We're considering staff-curated -vs- user-generated & curated content & we opt for the user-gen approach as we don't think the first option will scale. As we get into the market, we quickly realise the demand for content is high, we're in a good position to adjust our pricing upward, but engagement in content-provision & curation activities is low. So we decide to pivot to staff-curation.
The above pivot doesn't involve a radical product change (the offering remains similar overall), but does involve radical technical changes under the hood. A long-term-planning oriented company may have invested heavily in building robust (expensive & complex) community features that may be thrown out later. A short-term-planning oriented company would more likely hedge their technical decisions - leverage some 3rd-parties temporarily during user-testing, maybe test earlier, be more sensitive to priority changes.
