This will prevent that we build a kernel for both 3430sdp and any
35xx-based board, right ?

why removed ARCH_OMAP3 ??

Yes. But 3430SDP will not have any of 35xx processors; changes may seem minor but may play difficult someday.

Not really removed; I felt it was duplicated as choosing ARCH_OMAP3 does an automatic "select" fir ARCH_OMAP3. see:

+config ARCH_OMAP35XX
+	bool "OMAP35x Family"
+	select ARCH_OMAP3
+	select ARCH_OMAP34XX
+	select ARCH_OMAP3430
+	select NEON
