To read W3C XSLT 1.0 specification carefully, you will understand that it is
not a bug. Section 7.2 clearly explains that "Literal data characters may also
be wrapped in an xsl:text element. This wrapping may change what whitespace
characters are stripped (see [3.4 Whitespace Stripping]) but does not affect
how the characters are handled by the XSLT processor thereafter.", and the
referenced section 3.4 explicitly says such whitespace-only text node is
stripped:

<quote>
A text node is preserved if any of the following apply:

    * The element name of the parent of the text node is in the set of
whitespace-preserving element names.
    * The text node contains at least one non-whitespace character. As in XML,
a whitespace character is #x20, #x9, #xD or #xA.
    * An ancestor element of the text node has an xml:space attribute with a
value of preserve, and no closer ancestor element has xml:space with a value of
default.

Otherwise, the text node is stripped.
</quote>

Moreover, .NET does remove such whitespace text. Here is a repro xsl:

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/foo">
<xsl:text> </xsl:text>
</xsl:template>
</xsl:transform>

and instance:
<root />

If .NET still outputs whitespaces, then there is a bug *in .NET*, not in Mono.
In such case, you should file a bug against Microsoft.
