2021 phylogenetic tree of Nanopore library kits

It's that time of the year again. It is time for my annual phylogenetic tree of Nanopore library kits. It should be pretty self-explanatory. The devices are:

F - Flongle
M - MinION
G - GridION
P - PromethION

Note that the LSK109 kit will be discontinued on Sept. 10 2021, except for all COVID-related projects which will be supported indefinintely.  Please let me know if you spot any mistakes or have suggestions for imprevements.
