over 1000 packages starting with S

[oxinabox]

#78672 happened again. About 1 year later
We once again have over 1000 packages starting with S causing github not to display all folders

Options from #78672

1. Move to 2 layers of folders: A/B/Abacus.jl
2. Move to 2 letter prefixes: Ab/Abacus.jl
3. Move all JLLs to own folder (done)

Either of these options would shunt the problem down the road for a few more years

Here is break down of the states for counting up packages by the first two letters of their names:
(ignoring cases where there are none)

julia> using DataStructures, StatsBase

julia> packages = sort([lowercase(x["name"]) for (_,x) in TOML.parsefile("Registry.toml")["packages"] if dirname(dirname(x["path"]))!="jll"]);

julia> summarystats(collect(values(counter(x[1:2] for x in packages))))
Summary Stats:
Length:         486
Missing Count:  0
Mean:           19.197531
Std. Deviation: 35.549154
Minimum:        1.000000
1st Quartile:   2.000000
Median:         4.000000
3rd Quartile:   19.000000
Maximum:        302.000000

julia> for (x,y) in counter(x[1:2] for x in packages)
           y>100 && println("$x=>$y")
       end

Mose pointed out that cargo does 2 layers of 2 letter prefixes, populated on registration.
(so combo of option 2)

"If in doubt, copy Cargo" is always good advise for a package management I think

For the sake of still being able to still see the readme without excessive scrolling, what about A/BA/Abacus.jl?

[PallHaraldsson]

what about A/BA/Abacus.jl?

Rust/Crate seems to plan on having way more packages then Julia with ab/ac/abacus... :-/ [and only support lower-case] But at least since we are changing I support as you proposed, forced to upper case, not A/ba/abacus, maybe even just A/B/Abacus enough(?), because while we have ASCIIbetical ordering A-Za-z, and Aa-Zz is better, I think we can't work against it except as you suggested:
