1) May not work over wireless LAN devices?
I guess it depends on wireless technology, but 802.11xyzzy comes with an encryption solution already so isn't really a target of interest.
2) Needs a centralized key server.
Not really, implementation detail.
3) May not be supportable on all devices?
Definitely not supported on all devices, you tend to pay extra, but getting an increasingly small premium to pay. May become essentially free, depending on demand.
Purported to be faster on the LAN than IPsec because MACsec is on layer 2.
Speed doesn't have anything to do with layer2 or layer3, you may be assuming that ipsec is software and macsec is hardware which may be true, but is implementation detail. For example Juniper Trio can do some forms of IPSEC on the same hardware as MACSEC at the same performance profile. It is not exactly new technology, these devices have existed for +decade now? -- ++ytti
