It is intended as a feature, but might turn out to be not "the right
thing".

This is the case if you want to produce *visible* space in the output.
However, there is no way you can tell LyX to generate a space character
in the latex code.
In most circumstances, this is not a problem because TeX ignores
whitespace in math mode. However, some extensions and packages depend on
whitespace for disambiguation.
Example: Package icomma cannot be used with LyX (short of using ERT
*instead* of a math box) as it relies on input in the form
$f(x, y) = 3,45$ to disambiguate a decimal separator from a variable
separator and generate the correct spacing. (German typography uses the
comma as decimal separator.)
\usepackage{icomma} % Komma als Dezimaltrenner (im Mathe Modus)
% Standardmäßig läßt LaTeX im Mathe Modus immer etwas
% Platz nach einem Komma, für 3,45 etc. ist das falsch.
% Mit icomma gilt:
% Wenn auf das Komma ein Leerzeichen folgt, soll auch
% eins kommen, wenn nicht, schreibe es als Operator:
% z.B. $f(x, y) = 3,45$
% Geht nicht mit LyX, da der Leerzeichen in Mathe
% unterdrückt.

This will not allow you to generate the LaTeX code $f(x, y) = 3,45$.
