There is a small but relatively successful funding happening right now.
The Open Geospatial Consortium (OGC) is organizing a code sprint
conjointly with ASF and another open-source organization (OSGeo) [1].
For this code sprint, OGC and OSGeo solicited their sponsors, but ASF
could not (probably not the ASF way, and also geospatial may be too much
a niche domain at ASF). The collected money goes to participants [2].
This is small (10,000$ a few weeks ago, I do not know the amount today)
and only for short events, but this is the second year that this event
happens and if successful enough, it may continue to happen next years.
The advantage is that OGC takes in charge a lot of the burden of
organizing those events. I wonder if ASF should participate to the calls
for sponsors if such code sprints happen again, with some filtering for
bothering only those who have an interest in the target domain
(geospatial in this example).
