Wrong, I would actually say that the massive fail should be blamed on your plugin developers. It's not like 64 bit technology was just discovered the other day....if these guys can't be bothered to rewrite some code and update their plugins after 4 years, perhaps it's time to dump them!
From what I gather, there are older 32-bit plugins that have been abandoned by the developers, and will probably never see a 64-bit version, let alone an update of any kind. Some people have come to depend on these plugins and maybe have not found alternatives that provide something equivalent, so expecting some kind of solution to be able to continue using them is not unreasonable. Sure, you can blame the plugin developers for abandoning their software, but that doesn't solve anything.
If Logic supported VST plugins, you'd be able to use jBridge, but Logic only supports Apple's own Audio Units. The only workaround I know of is to Rewire to an app that supports 32-bit plugins (either on it's own or through jBridge) and can be a Rewire device. Logic has never been able to be a Rewire device (but can be a host), otherwise you'd be able to rewire Logic 9 to Logic X, so the DAW you rewire has to be something else.
Edit: Apparently Viena is a workaround, and probably the most ideal option.
Personally, I don't use any 32-bit-only plugins, but I think it's reasonable to want a solution to this problem. I also don't use Logic much anymore, Ableton Live is currently my main DAW. Ableton Live can be run in either 32-bit or 64-bit mode, but they actually still recommend using it in 32-bit mode unless you start running out of memory (and you can use jBridge in either mode - 32-bit mode to get 64-bit plugin support, or 64-bit mode to get 32-bit plugin support).
