+# ^^ simsimd is not enabled at the moment. Reasons:
+# - Vectorization is important for raw scans but not so much for HNSW. We use usearch only for HNSW.
+# - Simsimd does compile-time dispatch (choice of SIMD kernels determined by capabilities of the build machine) or dynamic dispatch (SIMD
+#   kernels chosen at runtime based on cpuid instruction). Since current builds are limited to SSE 4.2 (x86) and NEON (ARM), the speedup of
+#   the former would be moderate compared to AVX-512 / SVE. The latter is at the moment too fragile with respect to portability across x86
+#   and ARM machines ... certain conbinations of quantizations / distance functions / SIMD instructions are not implemented at the moment.
