Well - instead of this random pick of a reason, why not use AI to build a tiny AI app that has the roadmap as context, and provides educated answer?
Assuming a PM cannot comprehend entire roadmap, vision and details in their head, simply have the answer based on merits.
This is the intercom post from 2013 on the same topic - https://www.intercom.com/blog/product-strategy-means-saying-...
Anyway, copied the "reasons" here in case you want to use it locally. e.g.
## bash:
shuf -n 1 why-not.txt
const sampleData = [
{ "text": "Let's add that to our discovery backlog" },
{ "text": "What problem are we trying to solve?" },
{ "text": "That's an interesting perspective for our long-term roadmap" },
{ "text": "Let’s park that idea for now" },
{ "text": "That’s worth considering once we have more resources" },
{ "text": "We should validate that with users first" },
{ "text": "Can we revisit this after the next sprint?" },
{ "text": "It’s a great thought, but let’s prioritize our current goals" },
{ "text": "I’d like to hear more thoughts on this from the team" },
{ "text": "Let’s circle back after we’ve tackled the core priorities" },
{ "text": "We need to ensure alignment before moving forward" },
{ "text": "That might be more relevant in the next planning cycle" },
{ "text": "We should let this marinate a bit longer" },
{ "text": "Let’s pencil it in for further discussion later" },
{ "text": "Let’s table this for now" },
{ "text": "That’s a good thought, but let’s revisit it later" },
{ "text": "Let’s keep this in mind for future consideration" },
{ "text": "We’ll need to assess this in the context of our current objectives" },
{ "text": "Let’s put this on the back burner for now" },
{ "text": "Interesting idea, let's explore that next quarter" },
{ "text": "We should prioritize getting feedback from stakeholders first" },
{ "text": "This might be a phase two initiative" },
{ "text": "That could fit in a future roadmap iteration" },
{ "text": "We’ll need to revisit this once we’ve hit our milestones" },
{ "text": "Let’s gather more data before moving forward" },
{ "text": "I think this could be valuable down the line, let’s revisit then" },
{ "text": "Let’s schedule a follow-up on this when the time is right" },
{ "text": "This could be part of a larger initiative, but let’s hold off for now" },
{ "text": "Let’s focus on the immediate deliverables first" },
{ "text": "We’ll circle back once we have more clarity" },
{ "text": "We already finalized our OKRs for H1 but if you throw it in the backlog maybe we can get it prioritized in H2 planning"},
