FWIW, I have looked at a number of reputable PSU suppliers, and found absolutely nothing else which explicitly covers the minimum current.

However, I find that ATX12V v2.4 is included in Revision 1.31 of Intel's 'Design Guide for Desktop Platform Form Factors', published in April 2013. [https://www.intel.com/content/dam/www/public/us/en/documents/guides/power-supply-design-guide.pdf] This appears to be the latest revision, and I note:

  * revision history says Revision 1.31 includes:

     * Changed 3.2.10 12 V2DC Minimum Loading to REQUIRED

     * Updated ... ATX12V Specific Guidelines to version 2.4

  * section 3.2.10 seems to:

     * REQUIRE +12 V2DC to operate down to 0.05A

     * and RECOMMEND that it operates down to 0A

So... I guess that a PSU which claims ATX12V v2.4 compliance should be OK ?
