Remote Write is a viable alternative in Prometheus and its drop-in replacements. I'm not a massive fan of it myself as I feel the pull-based approach is superior overall but still make heavy use of it.

The pushgateway's documentation itself calls out that there are only very limited cirumstances where it makes sense.

I personally only used it in $old_job and only for batch jobs that could not use the node_exporter's textfile collector. I would not use it again and would even advise against it.
