This is a bit analogous to saying "You should walk everywhere. No matter how far. Don't trust transportation, it's too much trouble"
I disagree that spending time on a framework specific bug outweighs the time the framework saved you. It may feel like that some days but more likely you would run into larger issues in your own codebase that take even more time to debug. Perhaps some fundamental flaw in how you structured it because you're building it from scratch without the benefit of a widespread community of contributors and testers...

Yes the whole thing comes down to knowing your codebase very well and having it well structured.
