Given free alloy to do so, theres no reason not to place a single shipyard in nearest anchorage or trade hub, by replacing one slot, then, when the repair station isnt needed, you change it back. Think a permanent secondary shipyard isnt all that useful.
Which is why you don't make it a big one, as it's not permanent. You are assuming that there is an anchorage/trade hub in the area. A trade hub might not have the spare module slot in any case, with range being so important.
You can't manufacture replacements/reinforcements from a captured base. Early/mid game, if your shipyard is 10 jumps away from the front line, that's a looooooong replacement pipeline. And because it is only starport size, it's only cost you 350 alloys and a bit of time. Once the frontier has moved, scrap it.
