A long mishnah: One who declares certain foods to be off-limits will have different restrictions, depending on the phrasing. Plus, how far into the future does one's vow extend? Also, when a husband swears off his wife's productivity. Or does so for a set amount of time (the same "until Pesach" deadlines that we've seen in the past). Note that the Gemara doesn't address the whole if the mishnah; rather, it focuses on the vow against the productivity of the wife's hands. Plus, the question of uprooting an onion during the 7th year (shemitah), for replanting in the 8th year. How does that growth have impact on what has been prohibited by the vow? Which raises the question, post-growth, can food lose its forbidden status?
