It gets important if the lifetime of your project is more than three 
months and is extremely important if more than 10 years. But, it depends.

I also might be wrong in terminology, anyway, there are many rules that 
make programmer's life easier, described in the literature from the old 
good "How to write unmaintainable code" to "The Art of Readable Code". 
And I hope there are a lot of recent books on this subject I did not 
track and read yet.
