It is insofar that it shows whether you have the preferences of a PHP 
amateur.  There are important implications if you write it in the *wrong* 
place, such as at the *supposed* end of library code, that may not be easy 
to debug.  PHP means “PHP Hypertext Preprocessor” (now).  Whitespace (space, 
tab, newline, etc.) outside of <?…?> that is not obviously visible is made 
*output* in PHP, and once output has been sent, you not only have whitespace 
in the output but also cannot send HTTP headers anymore 
(<http://php.net/header>).

Meaning that files dynamically generated with PHP are sent with the default 
“Content-type: text/html” even if the resource content is not HTML, which 
breaks downloads, generated or proxy-fetched images, compacted resources, 
and so on.  And if the content is HTML, it is very easy to force 
Quirks/Compatibilty Mode because the DOCTYPE declaration may not be on the 
first line anymore.

Yes, but that is missing the point here completely.  Again.

If you cared to read, which *again* you did _not_, there *were* explanations 
in my posting, and I did _not_ say that “this is how it must be done” but 
gave well-founded recommendations, now elaborated on here.

Again, *nobody* has suggested that you either *always* write it or *always* 
omit it.
