You can certainly log contact approaches if it turns you on to keep
track of them. But, a contact approach is not an "instrument
approach", and it's not conducted under "actual or simulated
instrument conditions". Therefore, it doesn't count towards the IFR
currency requirements of 14 CFR 61.57(c)(1)(i).
