ImmutableMap.ofEntries()

Currently, Immutable.of() supports only up to 5 key-value pairs. I suggest adding a new method ImmutableMap.ofEntries(Entry<K, V>...) similar to Map.ofEntries() that appeared in Java 9. This will allow creating ImmutableMap with any number of key-value pairs.

I also suggest making ImmutableMap.entryOf(K, V) public so it can be used in ofEntries():

ImmutableMap.ofEntries(
    ImmutableMap.entryOf("a", 1),
    ImmutableMap.entryOf("b", 2));

ImmutableMap.ofEntries() has been added in https://github.com/google/guava/commit/cd3b4197fb523bf26f9122492915006ad306b3f3. It’s now available since Guava 31.

… and constructing Entry objects that will immediately be discarded

In ImmutableMap.Builder.put() and ImmutableMap.of() there are also temporary Entry objects that are discarded.
