To be fair, like all things, there are limits. Obviously the heavy lifting in my statement was the "frequent" part. No system will ever cover 100% of all eventualities. That's just not possible. But, OTOH, for me, a working system will cover common actions most of the time.I'm curious: how would you feel about a system which tells you, "There shouldn't be any need for an <X>. If you really want one, you know what you want it for better than we do."* That is, a system which says, "This is where our rules stop (in this area). If you want a thing which steps beyond this rule, it would not be helpful for us to tell you how to do that. Only you can figure out what that thing is or means." So, the system is neither giving a resolution to an action without oversight (since it is not giving a resolution at all), nor demanding on-the-spot resolution of its mechanics (because, at least in this instance, there are no mechanics to resolve).
It is instead saying that there is no rule for a theoretically-possible option, because whatever you wish to achieve will be better implemented by you doing it yourself than by them giving you a fixed result.
*This is an actual quote from the 13A corebook, specifically where X is an epic-tier Linguist feat, if you're curious.
And, yes, that's vague, because, well, there's no real hard line here. "Well, it must work X% of the time before we consider it working" just isn't all that useful. OTOH, lots of systems have a sort of default mechanic to baseline actions. For example, Savage World's Rule of 4 where a 4 always succeeds. The only thing in question is what modifiers and what size of die are you rolling.
If the rules simply wash their hands of a situation, that could be the sign of a system not working. Sure, if it's a really corner case issue, then fine, no problem. But, take early versions of D&D. You had no rules at all for jumping. The system simply did not give you any baseline at all for how and how far a character could jump. So, you had fifteen different ad hoc systems for covering a very basic thing that comes up a lot in game. This is a system not working.
5e, generally, works. There aren't too many times the game comes to a crashing halt because no one at the table, including the mechanics, has any idea about how to adjudicate something. It does come up, and that's why we have a DM. For example, today the question of, "Can I stuff a corpse into a Bag of Holding using a Telekinesis spell" was an actual question during the session. The rules are largely silent on this. I don't think there's any really applicable rules for if you can stuff a corpse in a bag of holding, so, it's pretty much 100% DM's call.
But, I'm also going to say that this is not a question that comes up so often that it requires mechanics.
