The only lanczsos scaling I have come across in Gimp 2.10 comes from the gimp_gmic_qt plugin, http://www.gmic.eu One of the filters: Layers -> Multiscale Operator.
Always some snags, works in percentages not absolute pixel sizes and as the name 'multi' layers. You can get out 2 layers of the same size as a new image, effectively a single layer. The gmic operation could be scripted if required to make it more convenient. Not exactly the same as the equivalent Gimp 2.8 scale but close. Comparison attached.
