Any plan to support the new `IBufferDistributedCache` interface?

Hi all! Some users of my caching library FusionCache are using this IDistributedCache implementation as an L2, mainly in mobile apps and games. I was wondering if you are planning to add support for the new IBufferDistributedCache interface to get even better perf.

The short version of this change is "exactly the same thing, but without allocating a byte[] every call"; here's the SE.Redis implementation for reference: https://github.com/dotnet/aspnetcore/blob/main/src/Caching/StackExchangeRedis/src/RedisCache.cs#L694

Or the key bits from the SQL Server version (probably closer): https://github.com/dotnet/aspnetcore/blob/main/src/Caching/SqlServer/src/DatabaseOperations.cs#L313

Sure, this sounds like a decent feature to add. I'm not sure how often we'll be able to avoid allocating without looking into this further to see what the common usage patterns are like, but it's definitely worth considering!

Note: if you can't avoid allocating the right sized array in at least one direction (read, write), then there would be no advantage to implementing this new interface. The relevant mechanisms already use type-testing to use the most appropriate API available.
