I meant to make the point that frameworks come with a cost, which may get deferred for a while. Maybe that doesn’t matter. For PHP and Go specifically I don’t see the point since the languages have everything you need out of the box.
Bootstrap 3 is a perfect example of why you wouldn't pick a UI framework, if you have demands for pixel-perfect design or custom animations you'll be immediately battling the framework in those areas. That doesn't mean all frameworks are bad, like graphic designers rarely use MS Paint and draw each pixel because it would take forever, i.e. you're not being an efficient engineer. If you're building a house, why make bricks yourself, chop trees for wood, or forge custom roof tiles?
To me, PHP / Go are themselves abstractions of an enormous amount of complexity, so why stop there, why not go as high as you can imho, higher = less code?
When you work without a framework, you invent your own framework. It won't be as well thought through - guaranteed. When changes come in, the sheer amount of code means mistakes will be made and your code will slowly turn into spaghetti. If this is a custom FFMPeg conversion service - totally worth it. If it's CRUD, like how 90% of apps are CRUD, then it's probably a mistake.
As I told another programmer, using a framework doesn't mean you are a "semi-skilled" programmer (what elitism). It means you know you aren't special, you aren't smarter than other programmers, you know your own limitations, and know that using a framework other people understand (and keeping the amount of code to a minimum) is the best for your company and the project.
Yes, frameworks have some advantages as you listed. And they have disadvantages. Before doing the same thing over again with Laravel, or Goravel (the original topic of this thread) think hard about the trade-offs. Frameworks impose limitations, on both the application and the programmer.
