+   * <p>This balances trade-offs between compile-time / bytecode overhead and Android runtime AOT
+   * compilation:
+   *
+   * <ul>
+   *   <li><b>Upper bound</b>: Large switch methods risk hitting the "huge" method size limit for
+   *       Android that prevents AOT compilation in some versions of Android (b/77652521, generally
+   *       around 1500 cases). Additionally, ART decides whether to AOT compile a method based on
+   *       whether the path is "hot" at runtime; keeping switch methods reasonably small ensures that
+   *       a single hot case does not force ART to compile a disproportionately large method and
+   *       consume extra runtime memory.
+   *   <li><b>Lower bound</b>: Making the number too small results in many small helper methods,
+   *       which increases classfile / bytecode size, constant pool overhead, DEX method count, and
+   *       javac attribution time (b/549228393).
