Hello.

> How about just switching to curl, instead
> of playing around the legacy stuff as wget is?

1. wget is not legacy. cURL and wget were initialy released at about the
same period, in 1996 [0] [1]; both saw their latest release in March 2024.
Hard to say that wget is legacy without saying so for cURL.

[0] https://en.wikipedia.org/wiki/Wget  => January 1996
[1] https://en.wikipedia.org/wiki/CURL  => November 1996

2. cURL can be configured without FTP support [2], so if switching from wget
to wget2 was done, knowing that FTP was dropped, and considering that was
acceptable on the basis that FTP is legacy (broken, insecure...), then it
is not inconceivalbe that distros may consider truning FTP off in their builds
of cURL, ion the same basis (broken, insecure...). Switching to cURL would
not solve the issue. Yes, it is a bit far-fetched, but given the reasoning
behind wget2 switch, it is legit to consider it for other tools that are not
FTP-only.

3. Existing packages (in external trees) may use wget's authentication options
yo authenticate to an HTTP server; switching to cURL would break them. That
also applies to existing (def)config files that use non-standard options, like
--no-proxy to talk to internal servers, or --load-cookies with a pre-build
script that authenticates against an internal server or filled by a CI/CD
job, etc...

4. For all things HTTP-related, wget2 is expected to be option-compatible with
wget.

5. As a consequence, it feels more appropriate to keep using wget for HTTP/S
downloads, and use a tool dedicated to FTP for FTP downloads, and implemented
as a separate backend in Buildroot.
