What's the issue there?
It should really have have a return type of item()*, and the param
should really be called 'node-list' rather than 'context':
<xsl:function name="f:apply-templates" as="item()*">
<xsl:param name="node-list" as="node()*"/>
<xsl:apply-templates select="$node-list/>
</xsl:function>
anything else?
One possible issue is that people may want the results to correspond
to the sequence order of the argument.
This could be "assured" if you use:
<xsl:for-each select="$node-list">
<xsl:apply-templates select="."/>
</xsl:for-each>
However, if you use this apply() function in:
/a/b/f:apply()
the results will be deduplicated and sorted in document order. If new
nodes are created, their order will be unpredictable
(implementation-dependent).
It is still OK to use such a function within an XPath expression if
order and deduplication don't matter, though.

If you needed to call apply-templates using a function call (say as
part of an xpath) any reason why this wouldn't be fine:
<xsl:function name="f:apply-templates" as="node()*">
<xsl:param name="context" as="node()*"/>
<xsl:apply-templates select="$context"/>
</xsl:function>
with:
<xsl:sequence select="f:apply-templates(child::node())"/>
(ignoring modes and params etc)
Seems ok to me...
Except when you use it as the second operand of the / operator.
