[2020] Will material caches be improved? Jagex not answering

I just watched the stream and many questions were answered, though one of the most commonly asked questions was not answered;

Will caches be improved?

Material caches right now are a nightmare to use. Unless you're someone pumping millions into the skill, you're required to stop excavating and head to material caches to complete your items. I'm fine with that - I actually like it.

The problem is that we've gone back in time and made it competitive. If there's less than 3 caches, you'll likely be stood waiting for respawn. If there are two or more people there, you'll be waiting much longer as the caches run out extremely quickly.

Personally I'd like to see caches either modified to ensure always one cache is active at any given time, or that they are based on individual players rather than the collective group mining them or even changed to work like how ores operate.

Could we get a response on if there are improvements being made? As it stands, it's the most frustrating part of this otherwise wonderfully developed skill.

Thanks!
