Yes of course. This is the deepest violation of generally accepted conditions. Following standards means 1) discipline, 2) organized code according to the rules that others follow, 3) Your code is suitable for use along with others on this standard, 4) Makes life easier when working in a team and. etc.
Yes, maybe it works. Yes, it can be a cool code. But it is difficult to maintain it as it grows. Every time you have to climb into it to understand where everything lies. And most likely you will refuse it later on.
Imagine a situation. You and 3-4 people are assembling cars. They are by standards (steering wheel in front, pedals under your feet, and so on). And you, because you took it into your head. Buyers come up and naturally begin to ask you - Where are the steering wheel, the pedals ...? You - Yes, over there and there. Guess whose machine they will use 3 times :) Do not be a crooked programmer whose slogan is one - There is nothing so pure and light that you can’t take it by hand.
Initially, you will experience discomfort, this is natural. And remember that these standards are not invented by stupid people. Those who probably have more experience and knowledge.
So my advice is to use the standards that smart people invented it more correctly. I hope to help. Good luck
