ReCaptcha integration in an KDE application

[Carl Schwan]

Hello folks,
Tobias and I are developing a KDE matrix client using Kirigami
and other KDE frameworks called NeoChat. This is a fork of another
QML and now unmaintained Matrix client named Spectral.

Tobias is currently implementing the account registration API
and we found out that even if it isn't mandatory in the matrix
spec, it is required to add ReCaptcha for connecting to most
of the Matrix server (including kde.org, matrix.org and other
major matrix servers).

>From a technical point of view, this would be quite painful to
implement (adding a dependency to QtWebEngine) but most
importantly this would require adding integration into a service
that is not privacy-friendly, proprietary and monopolist. This
is something that we think goes against the value of KDE. But at
the same time, making it possible to register an account directly
from NeoChat is something that is quite important in the user
experience.

So my questions to the community would be to know if there are
already some precedent of KDE apps adding supports for ReCaptcha
and if this is a good idea to support it?

Thanks in advance for your answers,
Cheers,
Carl and Tobias
