It's mostly because it's was a different scarce resource at that time that was seen as non-optimal use by the players, the courier. It can ferry item to you, in a normal game there was only one of them for your whole team, which mean using it would take that ability away for your teammate during the ferry time.

One constraint to those showmatches at the time was that every heroes had their own courier, and player at that point were not accustomed to using it for "low value" travel, unlike the AI that was using it liberally.

In a later patch, the 1 courier per hero feature was added, and now pro players are much better at managing it, but at that time it was truly a heavy opportunity cost.

The thing is even locals will have a greater time during the nicer times. Using Montreal, where I was living until a few years ago, is a much nicer place to wander around when there's no snow. It's a colourful city, lively and full of small and big activity to do, so you can get by with the sort of tourism you described in high season (summer), but also end of spring and early fall.

In the winter, it's a cold, wet and relatively low interaction time of the year. I assume some place have a high, low and dead season for tourism, and I personally aim for low, but to each their own. Quebec in general is a great place for winter vacation, just have to go outside Montreal island.

When an entry can belong to 0 or 1 related object only. Not that I'd put a constraint in such scenario, but I imagine a User can optionally have a Subscription, so subscription_id is either nil or present, and said subscription cannot be associated to any other User.

Double quotes allow you to do string interpolation, which is not possible with single quotes. So I assume one faction argues that everything should be double quoted because it's does not matter if there's interpolation or not, while the other group would rather only use double quotes when necessary, otherwise use single quotes.

I'm personally part of the second group simply because my linter forced it, but at the end of the day, it's such a low impact we don't really care.
