Not really. It is quite the opposite. The IPS patching system has no safety. You can basically patch any rom using the given ips file, resulting in a bugged rom. At least 60 percent of all players, who have patched the games using my ips files, were patching it wrong on their first try.
The far better patch (than IPS) type to use is UPS. Similar system, but it has a crc checksum and will reject the original rom, if the crc doesn't match. Because of the header and various versions of the original roms (US, EU, J), this kind of checksum is mandatory.
Regarding the expansion. The only thing here is the Xdelta or anything which is using this system. You can also try the Doki patch creator, which I uploaded on this site a while back. It is using the xdelta system and makes a batch file which autoexecutes the patching, if the correct original rom is present. This should be suitable for beginners. Because of the crc check, which can not be ignored here, the resulting (patched) rom can never be bugged. Nor can you bug it with accidental double patching.
