People are using it, have had trouble in the past (and possibly currently on non-updated Windows core)

I did some testing of running MTR tests under windows 10/11 recently.

Extensive runs on 10.8/10.6 innodb, main, rocksdb --big-test all passed with the exception of replication STOP slave on 10.8 due to MDEV-25633.

Requirements:

• Docker desktop (there was probably a non-docker way but it was pretty easy)
• https://docs.microsoft.com/en-us/windows/wsl/install - wsl install (I did a 20.04 base)
• Windows update needs additional box checked for updating the wsl kernel
• sysctl kernel.pattern_core=core (defaults to otherwise)

Container build:

FROM quay.io/mariadb-foundation/mariadb-devel:10.8

RUN apt-get update && apt-get install -y gdb patch mariadb-test {other plugins?} && rm -rf /var/li {oldpackages} && chown -R mysql: /usr/share/mysql/mysql-test

Entrypoint:

chown -R mysql: /var/lib/mysql

cd /usr/share/mysql/mysql-test

gosu mysql ./mtr --vardir=/var/lib/mysql .....

Note: chown on mysql-test directory is because the test run patches the results file in place for test runs, ugly, but that's what's there.

Which comes to the integration question. The current rhel8 docker-library can certainly do a few steps to create a container, passed via quay or the ci.mariadb.org is some package format. Windows steps seen pretty simple to docker run --rm container as a test run.
