They should preferably be enabled for analyses, as they are very convenient for on the fly analyses. If this is not yet possible, they should not appear on the dropdown.

Apparently you are using a memory layer as input, right ? But the result would be similar with a virtual layer.
Actually with anything that is not loaded by ogr.
The rasterize algorithm expects a vector layer opened with ogr, but the dropdown displays any vector layer, whatever the provider.
Algorithms should somehow declare which types of vector layers they can read. Just an idea: an optional parameter to ParameterVector to list the acceptable provider keys ? Victor what do you think ?
