Does a debtor's post-conversion estate have to include property acquired by the debtor after the initial petition?

1207(a)(1) and 1306(a)(1) that could include in the estate property acquired by the debtor after the initial petition. See Koch v. Myrvold, 784 F.2d 862, 863 (8th Cir. 1986) (property obtained by the debtor after the original petition in Chapter 11 but before conversion to Chapter 7 does not belong to the post-conversion estate). While the provisions of Chapter 12 or those of Chapter 13 may have lent support to the appellee's position had the debtor's conversion arisen under one of those chapters, the absence of comparable provisions in Chapter 11 compels the contrary result.²⁰
