The other option is to ask your current employer if they would allow a rollover from your IRA into their plan. If it has been recently, you might be able to explain it as an indirect rollover from your old employer's plan.
But probably, yes, just suck it up. Roll it over as a fill-in up to your current tax bracket, or coordinate to do it in a minimum-income year. (Maybe bonuses are low, or commissions, or stack up your deductions to be able to itemize in a year) It will not only benefit you with tax-free growth, but it frees you up to do backdoor Roths in the future. Going the other way, you will just keep asking every year.
