Do we support MQTT over Websockets?

I think we added WS support back in the days when a lot of company firewalls blocked outgoing connections to port 8883.
Is this still the case?
If we have to support it, there is another layer of complexity (keepalive, SNI, ...)
iOS app supports it, mosquitto current version?

I knew of its existence in our apps, of course, hence the question. But your comment regarding support in Mosquitto is very good. I do not see compiled in Websocket support on the Debian package:

$ ldd /usr/sbin/mosquitto
	linux-vdso.so.1
	libwrap.so.0 
	libsystemd.so.0 
	libdlt.so.2 
	libssl.so.3 
	libcrypto.so.3 
	libm.so.6 
	libcap.so.2 
	libc.so.6 
	libnsl.so.2 
	libgcrypt.so.20 
	liblzma.so.5 
	libzstd.so.1 
	liblz4.so.1 
	/lib64/ld-linux-x86-64.so.2
	libtirpc.so.3 
	libgpg-error.so.0 
	libgssapi_krb5.so.2 
	libkrb5.so.3 
	libk5crypto.so.3 
	libcom_err.so.2 
	libkrb5support.so.0 
	libkeyutils.so.1 
	libresolv.so.2 

And that immediately closes this case, as we do NOT want to build special packages.
