Should also mention online-only installers a la vs_buildtools from MS and a whole lot vendors more.

Want an offline installer? Easy peasy, just

- find one in a cobweb-covered thread in an obscure subforum on a vendor's site;

- manually compile a list of thousands of workloads your build tools would need, including optional ones, and create an offline installer yourself - using another machine that still has to be online - which will fail anyway if your target machine happens to be really offline;

- be told to basically GTFO for being an outmoded Luddite who opposes The Progress.
