Counter vs Timer in C - PIC MCU

I’m sure it’s best practice to use a timer for let’s say button debouncing logic.

But I have some simple code that just counts inside the main while loop.

Are there any big disadvantages to doing that?

I think it is quite OK to make bounce protection based on a counting variable in a simple application. The main disadvantage of this it's a difficulty of preserving the timing characteristics of the debouncing if the application needs to be grown in the future. Also you can't implement powersaving logic while waiting for timer interrupts.
