Surely the default went back to 0 (effectively unlimited) long ago?

2253.   [func]          "max-cache-size" defaults to 32M.
                        "max-acache-size" defaults to 16M.

got into BIND 9.5.0, but

2457.   [tuning]        max-cache-size is reverted to 0, the previous
                        default.  It should be safe because expired cache
                        entries are also purged. [RT #18684]

was there before 9.5.1, and AFAICS it has been like that ever since.
