As described on the official SMW page,

$smwgQMaxInlineLimit is a configuration parameter that sets the maximal number of rows ever printed by a single embedded query on a single page or a query on special page "Ask", even if a value for the limit parameter was specified explicitly. The configuration parameter was introduced in Semantic MediaWiki 1.0.

Note that the limit set with this configuration parameter does not apply to result format "Count".

Defaults to 500, which I realised while testing things out at ExpandTemplates late this morning. For wiggle room as concerns my conlang stats, I suggest between 750 and 1000--so long as we don't exhaust the servers.

Cf. an earlier, more ambitious attempt last month by @BlackHawk (T9738).

Also on this contributor's roadmap:

• Semantic Result Formats (T9287#197079), pending feedback for a Miraheze-specific compatibility patch at GitHub
• PdfBook, whose repair UO may soon look into (per T9755#197325)--but whose Unicode compatibility remains in doubt
• Score, now on the long-term backburner unless demand/interest perks up; I might as well like it to come to my site in the next 1-2 months (T5863)
• Renewing RegexFunctions after infrastructural/SRF issues have been sorted out; already disabled per T8866
