Like anything else, it's good to know how to do it in many different ways, it may help you down the line.

In production in an oddball environment, I have a python script to ftp transfer to a black box with only ftp exposed as an option.

Another system rebuilds nightly only if code changes, publishing to a QC location. QC gives it a quick review (we are talking website here, QC is "text looks good and nothing looks weird"), clicks a button to approve, and it gets published the following night.

I've had hardware (again, black box system) where I was able to leverage git because it was the only command exposed. Aka, the command they forgot to lock down and are using to update their device. Their intent was to sneakernet a thumb drive over to it for updates, I believe in sneaker longevity and wanted to work around that.

So you should know how to navigate your way around in FTP, it's a good thing! But I'd also recommend learning about all the other ways as well, it can help in the future.
